Accredited Drug Testing offers comprehensive hair follicle drug testing services in Johnstone, Texas. If you're in need of a hair drug or alcohol test, Accredited Drug Testing specializes in hair testing, providing testing centers across all cities Nationwide to perform hair tests. Generally, 1.5 to 2 inches of hair from your head or body may suffice. Hair analyses can identify drugs, alcohol/ETG, or other tailored testing options.

Recently, drug testing has increasingly turned to hair follicle tests. Many employers, legal bodies, and Substance Abuse experts now favor hair tests over traditional urine screenings. Employers with zero-tolerance drug policies, courts, and probation officers utilize hair follicle tests due to their extended drug detection window, lasting up to 90 days. Despite this, urine tests remain more accurate for drug screening within the past 5 days.

What it is, How it works

Hair analysis has emerged as an effective means for uncovering substance and alcohol consumption. Hair strands offer an extended timeline of drug and alcohol ingestion by capturing biomarkers within their structure as they grow. When extracted near the scalp, hair can reveal substance history up to about a 3-month period. Hair is straightforward to gather, tough to tamper with, and easy to send.

A hair sample of 1.5 inches in length, composed of roughly 200 strands (similar in size to a #2 pencil) taken nearest to the scalp, provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional requests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair can be collected. References to head hair are solely about scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

Key stages in the lab analysis of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves introducing a sample into a lab’s database. This stage ensures the sample was sealed and transported appropriately, assigns a unique LAN (Laboratory Accessioning Number), and concludes any supplemental data input not covered by an electronic chain of custody system.

Screening provides a preliminary quick inspection for substance abuse. Although Screening is cost-efficient for excluding drug use across most samples, confirming a positive outcome is necessary for it to be court-admissible. Any samples showing preliminary positives during Screening must undergo further confirmation.

When a sample returns a presumptively positive result during Screening, additional hair is extracted from the initial sample and readied for Extraction. During this phase, substances are extracted from hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), which makes hair testing one of the most intricate methodologies.

Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are cleansed before confirmation as required. The full lab procedure from Accessioning to Confirmation is inspected according to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Comprehensive detection duration: Hair drug tests can identify substance use up to 90 days, unlike urine tests that offer a narrower detection span.
  • Hard to falsify: Falsifying a hair drug test is particularly challenging, ensuring accuracy in results.
  • Offers historical insights: This testing method uncovers a trend of drug usage over an extended period, not just recent activity.

Limitations:

  • Unable to detect recent intake: Detection of drugs in hair takes approximately 5-7 days after usage.
  • Expense: Generally, hair drug tests have higher costs compared to other testing approaches.
  • Result variability: Influences like hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the actual examination involves the hair strand itself, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing drug testing methods in Johnstone, TX, hair follicle testing clearly surpasses urine testing. While traditional urine tests detect recent drug use, hair tests can identify usage over a history up to 90 days.
